wifi: iwlwifi: exit eSR only after the FW does

[ Upstream commit 16867c38bcd3be2eb9016a3198a096f93959086e ]

Currently the driver exits eSR by calling
iwl_mvm_esr_mode_inactive() before updating the FW
(by deactivating one of the links), and therefore before
sending the EML frame notifying that we are no longer in eSR.

This is wrong for several reasons:
1. The driver sends SMPS activation frames when we are still in eSR
   and SMPS should be disabled when in eSR
2. The driver restores RLC configuration as it was before eSR
   entering, and RLC command shouldn't be sent in eSR

Fix this by calling iwl_mvm_esr_mode_inactive() after FW update
